Minimum SDK version for USBD?

[Julie H]

I'm still using SDK 12.3 on a nRF52840 product and am bashing my head against the wall because of issues with the USB driver. The current problem is all manner of hard faults trying to enable the USB driver itself. For example, the __DSB() macro in nrf_usbd_pullup_enable() causes a hard fault the first time I invoke app_usbd_start().

I'm also using s132. I know I need to update all the things, but I'm putting that off until I run into a wall and upgrading is easier than not.

Regarding your other question (i.e. usb driver), can you take a look at the usbd_hid_generic example under the peripheral folder in SDK 12.3 (or in SDK 14)? Could you please see if that example works on your device prototype. If the usb driver doesn't work, I think it's best if you could open up a myPage case. They will be able to help you further there. Hope that helps a bit!
